Investigation of Cavity Flow Effects on Store Separation Trajectories

Abstract

In this study, a cavity previously used as part of the Navy Internal Carriage and Separation (NICS) experiments will be used in conjunction with the Mark 82 (500 lb class) store to compare previously obtained wind tunnel data to CFD results for an internal bay/store configuration. Forces and moments for the store along the horizontal traverse will be found using a specific single equation turbulence model (Spalart-Allmaras) in order to better understand the nature of the flow and its affect on the store with an emphasis on the region in the vicinity of the shear layer. The CFD results will be compared with existing wind tunnel data on the same configurations in order to jude the efficacy of using Euler, Navier-Stokes, and time-accurate Navier-Stokes flow solvers to provide mean force data for the store.
